Abstract
The electric conduction of NH3K3-xRbxC60 was studied using the cavity perturbation technique. It was confirmed that (NH3)K3-xRbxC60 was insulating between 4.5 and 250 K. Conductivity of (NH3)K3-xRbxC60 at 200 K was found to be 3-4 orders of magnitude smaller than those of K3C60 and (NH3)NaRb2C60. Difference in conductivity of these materials showed that metal-insulator transition (MIT) in A3C60 systems was driven by the reduction of lattice symmetry from fcc to fcc.
